System and method for providing a two-way interactive 3d experience

ABSTRACT

A system for providing a two-way interactive 3D experience includes a first video capture system configured to capture a first set of images of a first person in a first location, and a first display system in the first location. A second video capture system is configured to capture a second set of images of a second person in a second location. A second display system is in the second location. A two-way communication link is configured to deliver the first set of images to the second display system for display and deliver the second set of images to the first display system for display. The second display system is configured to generate a substantially life-sized 3D display of the first person based on the first set of images.

BACKGROUND

Multiple projector systems have been developed to project multiple videoimages to a common display location, such as a screen or wall, toproduce a composite display. A composite display is one in which asingle image is produced using multiple projectors, with each projectorproducing a portion or component of the total image. These displaysystems can be configured to allow multiple sub-frames to overlapcompletely, not at all, or anything in between, or to provide multipleseparate composite images. Yet another application for a multipleprojector system is the production of three-dimensional (“3D”) images.

One challenge associated with composite images is consistentreproduction of color, brightness, etc., across multiple displays ormultiple channels on the same display. For example, brightness and colorintensity can vary within each individual portion of a compositedisplay, with the result that the composite image has noticeableirregularities. It can also be difficult to calibrate and reconfiguremultiple projector systems between various display configurations, suchas to allow content to flow across multiple screens in a single display,while also providing consistent brightness, color, etc.

Additionally, the production of 3D images using a multiple projectorsystem has typically been complicated and difficult.

For these and other reasons, a need exists for the present invention.

DETAILED DESCRIPTION

In the following detailed description, reference is made to theaccompanying drawings which form a part hereof, and in which is shown byway of illustration specific embodiments in which the invention may bepracticed. In this regard, directional terminology, such as “top,”“bottom,” “front,” “back,” “leading,” “trailing,” etc., is used withreference to the orientation of the Figure(s) being described. Becausecomponents of embodiments can be positioned in a number of differentorientations, the directional terminology is used for purposes ofillustration and is in no way limiting. It is to be understood thatother embodiments may be utilized and structural or logical changes maybe made without departing from the scope of the present invention. Thefollowing detailed description, therefore, is not to be taken in alimiting sense, and the scope of the present invention is defined by theappended claims. It is to be understood that features of the variousembodiments described herein may be combined with each other, unlessspecifically noted otherwise.

As used herein, the term “sub-frame” refers to that portion of a displayimage that is produced by a single projector. A complete display imageproduced by multiple sub-frames from multiple projectors is referred toas a “composite image.” It is to be understood that a composite imagecan be produced by a sub-group of projectors (i.e. fewer than all of theprojectors) in a multiple projector system.

One embodiment is directed to a system and method that uses 3D displaysand cameras to create life-sized and natural aspect ratio “celebritywall” experiences for immersive entertainment. One embodiment uses 3Ddisplay(s) and 3D camera(s) to create a life-sized, life-like 3Dexperience between at least two geographically dispersed locations(e.g., rooms in different buildings, different cities, different states,and/or different countries). One embodiment leverages natural aspectratios to provide a more immersive and interactive experience betweenpeople located at geographically dispersed locations, such as acelebrity and his/her fans.

Some embodiments include creating life-sized superwide displays thatprovide a just-like-being-there 3D courtside experience at a basketballgame or life-sized displays that demonstrate various 3D views of aclothing line for fashion/retail. Some embodiments augment theseexperiences by creating life-sized 3D displays of a more natural aspectratio that enable talent (e.g. celebrities, athletes, artists, and VIPs)to reach a much larger and more geographically dispersed audience.Furthermore, two-way 3D celebrity walls (including life-sized 3Ddisplays and 3D cameras) enable the sports athlete or artist to talk tofans virtually, as though just like being there. In some embodiments,this is expanded to support multiple locations, positioned andarchitected to make the virtual experience look natural. One embodimentextends the reach of the celebrity, drastically reduces travel costs,and creates a more compelling virtual experience. The system can also bea key differentiator to help with sales support, with lead designer(s)being able to talk through dress design with potential high endcustomers, showing one-of-a-kind dresses located in a different part ofthe world.

To achieve the life sizes for an immersive 3D display, one embodimentleverages multiple projectors to create a high quality, high resolution,seamless, and yet cost effective solution. Similarly, multiple camerasare used to capture imagery with appropriate resolution and aspectratio. Empirically, there is a more natural experience and analmost-life-like feeling when viewing images of people between 80% to120% actual size, in contrast to imagery on displays of typical sizesand aspect ratios. Moreover, scaling to the correct size and utilizing3D encourages so-called visual grazing to further create an immersiveexperience.

Some embodiments allow special guests the opportunity to interact withtalent in ways they have never experienced before. Utilizing life-sizeddisplays and 3D cameras, when the special guests interact with thetalent, they will have a true-to-life experience and the feeling ofactually meeting them in-person, without the talent actually being inthe same location.

In one embodiment, the primary fan site consists of a multi-projector 3Ddisplay system in a size and aspect ratio that are appropriate for thetalent. For example, the display would be about 5′×8′ to create alife-like experience of interacting with a professional athlete. Thedisplay solution creates a seamless 3D display in the appropriate aspectratio. Geometric and color differences among the projectors areautomatically corrected to deliver a high quality result. Likewise, onthe celebrity side, two or more cameras are used to form the appropriate3D imagery in an appropriate aspect ratio. For example, for a moreportrait oriented display, two portrait oriented high-definition (HD)cameras are used to capture portrait oriented HD 3D imagery. Providingdifferent aspect ratios involves using additional cameras to stitch andblend the various camera images to form the appropriate left-right eyepair matched to the display aspect ratio.

To create a two-way experience, additional displays and cameras are usedfor full duplex. 3D portals are used in one embodiment for eachadditional fan site. On the talent side, the viewing experience may be2D or 3D. Connection among the different sites may be facilitated usingvideo networks (e.g., multiple fiber/HD-SDI links) or data networks.Audio (microphones and speakers, including possibly directional) at eachsite is managed and interconnected. To create a natural multi-siteexperience, the positioning of the walls, the cameras, and theparticipants' relative views, are all taken into account. In oneembodiment, the cameras are positioned with respect to the walls in sucha way to maximize eye contact among sites.

“Portrait wall” or “celebrity wall” embodiments of different sizes havebeen constructed, up to 9′ tall, using 3D display systems with 6-8projectors seamlessly blended and tiled together, coupled with twoportrait oriented cameras to create a live two-way 3D capture anddisplay system with audio.

One embodiment facilitates a real-like 3D video communication betweenthe celebrity/talent site and the fan site(s). It also could be designedto enable a one-to-many experience, so that the talent could beinteracting with multiple fan sites simultaneously. The “fan” experienceis life-sized (life-like and immersive) and uses a natural aspect ratio(more portrait appropriate for a single person). Many applicationsinclude sports, concerts, gaming, and fashion/retail. This is a uniquebenefit for the talent and special guests. The talent will be able toreach out to more people and the special guests will have greateraccess.

One embodiment uses scalable camera and projector arrays to deliver highquality, life-sized, immersive content. In contrast to standardentertainment formats such as 16:9 HD and 2.35:1 cinema, other aspectratios are used to bring an enhanced 3D experience. One embodiment usesa wider panoramic 5:1 view with sufficient resolution to deliver theentire field of view (e.g., the full length of a basketball court or thebreadth of a concert stage), which gives a closer approximation to thein-arena experience. The fan watches the action move across the screenrather than having the screen follow the action. As with the real venue,they are free to let their eyes explore—to the scoreboard, players onthe sidelines, cheerleaders, other local attendees, etc., all withsufficient resolution to be naturally drawn into the 3D scene.

Scenarios for the techniques described herein include, for example, thefollowing: (1) Enticement for season ticket holders, to interact withtheir favorite player; (2) an opportunity for VIPs to have specialaccess; (3) celebrity Meet and Greet; (4) Interviews; and (5) pre-gameand post-game chalk talks. People that would be interested in using thetechniques described herein would include, for example, the following:(1) Fans wanting to “meet” their favorite player/performer; (2) teamowners wanting to enhance their fan experience; (3) event organizers whowant a unique experience for their customers; (4) corporate marketingpeople, who may use this to entice their clients; (5) performers whowant to interact with their fan base to help sell albums or tickets.

FIG. 1 is a block diagram illustrating a prior art multi-projector imagedisplay system 100 suitable for use in various embodiments describedherein. The image display system 100 processes image data 102 andgenerates a corresponding displayed image 114. The displayed image 114is defined to include any pictorial, graphical, or textural characters,symbols, illustrations, or other representations of information.

In one embodiment, the image display system 100 includes an image framebuffer 104, a sub-frame generator 108, projectors 112A-112C(collectively referred to as projectors 112), camera 122, and acalibration unit 124. The image frame buffer 104 receives and buffersimage data 102 to create image frames 106. The sub-frame generator 108processes the image frames 106 to define corresponding image sub-frames110A-110C (collectively referred to as sub-frames 110). In oneembodiment, for each image frame 106, the sub-frame generator 108generates one sub-frame 110A for projector 112A, one sub-frame 1108 forprojector 1128, and one sub-frame 110C for projector 112C. Thesub-frames 110A-110C are received by the projectors 112A-112C,respectively, and stored in the image frame buffers 113A-113C(collectively referred to as image frame buffers 113), respectively. Theprojectors 112A-112C project the sub-frames 110A-110C, respectively,onto the target surface 116 to produce the displayed image 114 forviewing by a user.

The image frame buffer 104 includes memory for storing image data 102for one or more image frames 106. Thus, the image frame buffer 104constitutes a database of one or more image frames 106. The image framebuffers 113 also include memory for storing sub-frames 110. Examples ofimage frame buffers 104 and 113 include non-volatile memory (e.g., ahard disk drive or other persistent storage device) and may includevolatile memory (e.g., random access memory (RAM)).

The sub-frame generator 108 receives and processes image frames 106 todefine a plurality of image sub-frames 110. The sub-frame generator 108generates sub-frames 110 based on the image data in image frames 106. Inone embodiment, the sub-frame generator 108 generates image sub-frames110 having a resolution that matches the resolution of the projectors112, which is less than the resolution of image frames 106 in oneembodiment. The sub-frames 110 each include a plurality of columns and aplurality of rows of individual pixels representing a subset of an imageframe 106.

The projectors 112 receive image sub-frames 110 from the sub-framegenerator 108 and, in one embodiment, simultaneously project the imagesub-frames 110 onto the target surface 116 at overlapping and/orspatially offset positions to produce the displayed image 114. In oneembodiment, the display system 100 is configured to give the appearanceto the human eye of high-resolution displayed images 114 by displayingoverlapping lower-resolution sub-frames 110 from multiple projectors112. These overlapping sub-frames can be spatially shifted or havearbitrary geometric transformations with respect to one another. In oneembodiment, the projection of overlapping sub-frames 110 gives theappearance of enhanced resolution (i.e., higher resolution than thesub-frames 110 themselves). Approaches have been developed fordetermining appropriate values for the sub-frames 110 so that theresulting displayed image 114 produced by the projected sub-frames 110is close in appearance to how the high-resolution image (e.g., imageframe 106) from which the sub-frames 110 were derived would appear ifdisplayed directly.

It will be understood by a person of ordinary skill in the art that thefunctions performed by the sub-frame generator 108 may be implemented inhardware, software, firmware, or any combination thereof. Theimplementation may be via a microprocessor, programmable logic device,or state machine. Components of the system may reside in software on oneor more computer-readable media devices. The term computer-readablemedia as used herein is defined to include any kind of memory, volatileor non-volatile, such as floppy disks, hard disks, CD-ROMs, flashmemory, read-only memory, and random access memory.

Also shown in FIG. 1 is reference projector 118 with an image framebuffer 120. The reference projector 118 is shown in hidden lines in FIG.1 because, in one embodiment, the projector 118 is not an actualprojector, but rather is a hypothetical high-resolution referenceprojector that is used in an image formation model for generatingoptimal sub-frames 110. In one embodiment, the location of one of theactual projectors 112 can be defined to be the location of the referenceprojector 118. The display system 100 can also include a camera 122 anda calibration unit 124, which can be used to automatically determine ageometric mapping between each projector 112 and the reference projector118.

The image display system 100 can include hardware, software, firmware,or a combination of these. In one embodiment, one or more components ofthe image display system 100 (e.g. the frame buffer 104, sub-framegenerator 108 and calibration unit 124) are included in a computer,computer server, or other microprocessor-based system capable ofperforming a sequence of logic operations. Such a system is generallyreferred to herein as a “controller” for the multi-projector system. Inaddition, processing can be distributed throughout the system withindividual portions being implemented in separate system components,such as in a networked or multiple computing unit environment (e.g.clustered computers).

While the embodiment shown in FIG. 1 includes three projectors, and onecamera, these quantities of components are only exemplary. For example,another embodiment of a multi-projector system 200 is shown in pictorialform in FIG. 2. This embodiment includes twelve projectors 202 a-l, alloriented to produce a single composite image 204 on a display surface206. As shown in this example, the twelve projectors produce twelvesub-frames, labeled 208 a-l, which in this figure are combined togetherto provide a single wide format composite image 204. While thesuperimposed sub-frames 208 are shown spatially offset from each otherin FIG. 2, this is for illustrative purposes, and does not necessarilycorrespond to the actual positioning of sub-frames to produce thecomposite image 204. It is also to be appreciated that the actualphysical location or grouping of projectors in a multi-projector systemcan vary. For example, while the projectors 202 in FIG. 2 are physicallyarranged in three groups of four and the sub-frames on the display aregenerally in three groups of four, the projectors could be arranged in adifferent physical position, and any of the twelve projectors 202 a-lcan be configured to produce any one of the twelve sub-frames 208 a-l.

The twelve projectors 202 are controlled by a controller system, whichcan be a computer, computer server, or other microprocessor-based systemcapable of driving the projectors to produce the composite image, asdiscussed above. The controller is designated generally at 210. However,as noted above, the controller system can include multiple computingdevices, such as a first controller computer 210 and a second controllerdevice 212 that is networked or clustered with the first controllercomputer. Similarly, the system 200 in FIG. 2 includes a camera 214 forfeedback and adjustment of the projectors 202, but can also includemultiple additional cameras 216, 218, which also provide feedback to thecalibration unit (124 in FIG. 1) that is associated with the controller210 or clustered controller group.

The multi-projector systems in FIGS. 1 and 2 are shown producing asingle composite image using all available projectors. However, it hasbeen found that it can be desirable to divide a group of projectors in amulti-projector system into sub-groups. Shown in FIG. 3 is an embodimentof a multi-projector system 300 in which the projectors 302 are dividedinto sub-groups, to produce multiple composite images 304, 306, 308 on abent backdrop-type screen 310. While this screen is shown as includingthree connected portions, it could alternatively include multipleseparate surfaces, each one addressed by a different sub-group. In thiscase, a first sub-group of three projectors 302 a-c provide threesub-frames 304 a-c that produce composite image 304, a second sub-groupof three projectors 302 d-f provide three sub-frames 306 a-c thatproduce composite image 306, and a third sub-group of three projectors302 g-i provide three sub-frames 308 a-c that produce composite image308. While the embodiment shown in FIG. 3 includes three screens, anynumber of multiple screens can be used. These multiple composite images304, 306, 308 can be produced using a single microprocessor controllersystem 312 (whether a single computer device, or multiple computers ordevices that are networked or clustered together), and can be relatedimages or independent images. The multiple composite images canrepresent multiple composite displays or multiple channels on the samecomposite display. At least one camera 314 can be oriented toward thedisplay screen 310 to provide feedback to a calibration unit (not shown)associated with the controller 312, in the manner discussed above.

As noted above, one challenge associated with producing composite imagesis consistent reproduction of color, brightness, etc., across multiplecomposite displays or multiple channels on the same composite display.This is particularly an issue where these displays are produced using asingle microprocessor system. It is generally desirable that a compositedisplay (as in FIG. 2) or group of composite displays (as in FIG. 3)have the same visual characteristics throughout (e.g. consistentbrightness, color). For example, it can be distracting for one image ina multi-screen display or one eye in a stereoscopic/3D display to differin color or brightness. Likewise, it can be undesirable if amulti-screen signage display having content that flows across thescreens exhibits differing brightness and/or color across the differentscreens.

Advantageously, the present disclosure provides various embodiments of asystem and method that have been developed to allow automatic deliveryof consistent imagery (e.g. consistent brightness, color, etc.) using amulti-projector composite display system across multiple screens and/ormultiple channels. This system and method is also useful for 3Dapplications. There are different techniques for displaying stereoscopic3D images. As is well known, stereoscopic 3D images involve left andright image pairs that are slightly different in perspective. When aviewer sees one image of the pair with the left eye and the other withthe right eye (typically with the aid of special polarized or colorfilter glasses), the effect can approximate actual human stereoscopicvision of three dimensional objects.

Some 3D projectors use time multiplexing to alternately display twochannels corresponding to left and right images. While these images canbe consistent in color and brightness (because they are produced by thesame projector), this is often obtained in a trade-off of bit depth andoverall brightness.

These types of projectors can also be very expensive. Alternatively,dual projectors can be used for stereoscopic 3D images. One projectorwill project the left image and the other will project the right image.Dual projector systems often require manual calibration and alignment,as well as balancing luminance and color so that the two channels areconsistent. These tasks generally require the services or highly trainedtechnicians, and can be time consuming. Also, these dual projectorsolutions typically have a fixed aspect ratio, fixed resolution, andfixed brightness.

Many prior 3D approaches can deliver at most two distinct views, and/orinvolve the use of 3D glasses. However, those of skill in the art willrecognize that some systems can be multi-view (i.e. deliver more thantwo views), and that autostereoscopic (not requiring glasses) displaysare also available. Autostereoscopic displays are commonly multi-view,and as a user moves his viewing position from side to side with respectto the display, the eyes receive a more appropriate pair of views togive a stereo/3D view. These displays are limited because they can onlygive a relatively small number of view zones (e.g. the object appears to“jump” in 3D as the viewer moves between view zones). Moreover, in orderto obtain these results, displays with optical elements are often used.Each view is produced by spatially multiplexing the available displaypixels (LCD or projected), thereby trading off the number of distinctviews/view zones and spatial resolution. For multi-screen solutions, itis not entirely easy to reconfigure the system to other displayconfigurations or to flow content across the screens. The display systemmay also be a full autostereoscopic continuous view 3D system.

Shown in FIG. 4 is a flow diagram illustrating a method for producingconsistent composite image characteristics across multiple displays ormultiple channels on the same display using a common microprocessorcontrol system according to one embodiment. In this method, the displaysystem is assumed to be a multi-projector display system like that shownand described in any of FIGS. 1-3, consisting of a collection ofprojectors, multiple graphic cards, one or more PCs clustered together,one or more calibration cameras, and one or more display surfaces. Thesystem could be easily configured to display multiple screenssimultaneously (displaying different content or even related content).

The first step 400 in the method is to divide the projectors intophysical sub-groups. The multi-projector system disclosed hereinincludes at least two sub-groups of at least one projector each.However, different numbers of projectors per sub-group and differentnumbers of sub-groups can be used. For example, the system shown in FIG.3 includes three sub-groups of three projectors. It will be appreciatedthat the sub-groups in a given multi-projector system can have differentnumbers of projectors in the sub-groups. For example, a system witheight projectors can be divided into two sub-groups with threeprojectors each, and a third sub-group with two projectors.

The projectors are grouped to cover the different screens or channelsthat are associated with the multi-projector system. Each projector isassigned to exactly one sub-group at any one time, though of course thesystem can be reconfigured when desired to reassign the projectors todifferent sub-groups. As noted above, the display system usescentralized resources (cameras, PCs, etc), and can be front- orrear-projected or both. Mixed projector technologies can also be used.For example, some projectors in the system can be LCD projectors, whileothers are DMD devices.

Once the projectors have been mapped to the different sub-groups, thenext step 402 can be to pre-calibrate the calibration camera(s) toaccount for differences from the underlying mathematical model. In oneembodiment, an amount of lens distortion for each calibration camera, aswell as the relative orientation and position of each camera, iscalculated using a known calibration pattern or chart. Once computed,the control system can precompensate each subsequently captured image toaccount for the lens distortion and relative geometry. The color spaceof the camera can also be corrected by pre-calibrating the camera usinga device like a spectrophotometer, and then pre-compensating capturedimages with color transformations.

In another embodiment, the vignetting effect is estimated and eliminatedfor each calibration camera. As will be appreciated by those of skill inthe art, light intensity detection can vary across the field of view ofa given camera. In particular, there can be a reduction in lightintensity detection at the margins of the image. It is desirable tocompensate for this “vignetting” effect (also called a luminance profileor intensity profile) for each camera. This compensation is oftenperformed by using a flat white physical target of known intensitycharacteristics. By viewing that pattern with each calibration cameraand measuring the luminance intensity variation of the resulting imagevia the calibration unit, this allows the system to estimate theintensity vignetting based upon spatial variation of intensity detectionacross the calibration pattern image. Once the intensity variation isknown, the control system can postcompensate each subsequently capturedimage, so that all images captured by that camera will not suffer fromthe vignetting effect. In this way, the camera(s) become pre-calibratedto give accurate comparative intensity readings.

As suggested by arrow 412 in FIG. 4, the process can move from step 400to step 404, without pre-calibrating the cameras. Whether the camera(s)are pre-calibrated or not, the next step 404 is to specify the targetcharacteristics between the sub-groups of projectors. Targetcharacteristics for each sub-group are specified with respect to one ormore of the other sub-groups. For example, it is desirable that theluminance profile and color gamut of sub-group #1 and sub-group #2 besimilar, or at least consistent. As another example, it can be desirablefor the sub-groups to conform to the same reference bounding box (e.g.for stereo 3D output). Thus, this step involves identifying theparameters and the constraint function(s) relating the projectorsub-groups.

In some cases, this step involves first using modeling and measurementsteps for each sub-group. Examples of these modeling and measurementsteps include calibrating the projection brightness of each sub-group tobe as uniform as possible. In one embodiment, the image pipeline for themulti-projector system uses a sophisticated image formation model andautomatic measurement steps via feedback through the calibrationcamera(s), including measuring the inter-projector geometry, luminance,color, black offset, etc. These modeling and measurement steps areoutlined in N. Damera-Venkata, N. L. Chang, J. M. DiCarlo, “A UnifiedParadigm for Scalable Multi-Projector Displays,” IEEE Transactions onVisualization and computer Graphics, Nov.-Dec. 2007, and in U.S. Pat.Nos. 7,306,341, and 7,443,364, and U.S. Patent Application PublicationNos. 2007/0091277, 2007/0097334, 2008/0002160, 2008/0024469,2008/0024683, and 2008/0143978, the disclosures of which areincorporated by reference herein.

As described in the above references, a series of patterns are projectedby a set of projectors and subsequently captured by the camera(s) toestimate the calibration parameters with respect to the imaging model.In one embodiment, based on the linearity of light, the model is asummation of each projector's light output, after undergoing anygeometric transformations, resampling, luminance variations, color gamutchanges, as well as inherent light leakage (or black offset). Onceestimated, the calibration parameters facilitate an accurate predictionof the projectors' final image. As described in the above references,desired target parameters (e.g. luminance profile for the entireprojector system, color gamut, etc) are chosen for the set ofprojectors, and rendering parameters for each projector are optimizedbased on the desired target parameters. The rendering parametersencapsulate the information needed to make each sub-group appear asthough the output came from a single projector (i.e. so that the outputappears seamless and achieves certain desired image properties). Forexample, this approach helps ensure that the geometry, luminance, andcolor of the resulting image are consistent throughout the set ofprojectors. In the system and method disclosed herein, each sub-group ofprojectors undergoes this modeling and measurement process.

Once the target characteristics for the sub-groups have been specified,the next step 406 is to determine the target parameters (brightness,color, etc) for each sub-group to ensure consistent rendering across allsub-groups. In other words, projection values for brightness, color,etc. are assigned to the projectors in the different sub-groups so thatthe final projected images are consistent between sub-groups withrespect to these parameters. In the example of multi-channelstereoscopic 3D, this step can include scaling down the brighter of thetwo target luminance surfaces corresponding to the “left” and “right”sub-groups. Normally with multiple projectors there can be brightnessdiscontinuities and seams, etc. In order to make the output frommultiple individual projectors appear as if it came from a singleprojector, one with a particular smoothly varying luminancesurface/profile, the target luminance surface of one sub-group may besubstantially brighter than one obtained for a second sub-group, so thiswould also need to be factored in during calibration.

As another example, the system can examine the chromaticity of theprojectors in each sub-group and take the intersection gamut of thecolor space of all the projectors in each sub-group to ensure that allcontent can be feasible in color. After the above measuring and modelingsteps are performed for each sub-group, the resulting calibrationparameters are adjusted so that the color gamut of one sub-group doesnot vary significantly from a second one, thereby ensuring consistencyacross sub-groups. The calibration camera captures these images, and thecalibration unit analyzes the chromaticity of the respective projectorto determine the full range of color values that the projector canproduce. When this is done for all projectors, the intersection gamutrepresents the full range of color values that all projectors canproduce. Information regarding the intersection gamut of availablecolors can be used to allow the system to select color values that arewithin the available color space for any projection color values thatmay fall outside that space. This allows a color that cannot beaccurately rendered by all projectors to be adjusted to the closestcolor within the common color space, so that all sub-groups project thesame color for a given color value.

Following the determination of the target parameters for the differentsub-groups, the next step 408 is to compute the rendering parameters forthe entire system using the parameters for each sub-group. For thepurposes of rendering, each sub-group is regarded as a separate“display”. The multi-projector system computes the projectiondifferences among the projectors in a given sub-group and then solvesfor the parameters needed to adjust each projector so that whencombined, the final result looks seamless and exhibits the desiredtarget characteristics. In one embodiment, a training algorithm isexecuted to efficiently compute these rendering parameters. This processis outlined in U.S. Patent Application Publication No. 2008/0024469. Inthe last step 410 shown in FIG. 4, appropriate display content is sentto each projector in each sub-group at display time. When it is desiredto display some content, the computed rendering parameters are appliedto every desired frame to determine how to adjust each projector's imageso that when projected in the sub-group configuration, the resultingimage achieves the desired characteristics. Because of the foregoingcalibration steps, the system can display distinct, related, oridentical content via each sub-group, with consistent displaycharacteristics in each sub-group. In this way, one can treat amulti-screen display as a connected display where the content can flowacross the sub-groups.
